Crash, Bang, Squelch! (CBS!) is the biggest single event of the CHaOS year, taking place as part of the Cambridge Science Festival. For Crash, Bang, Squelch! CHaOS brings 50 experiments into one place, for more than 2000 visitors to see during the day. In 2012, CBS! will take place on Saturday 17th March 2012, and were open to the public from 10am-5pm. Like all CHaOS public events, CBS! is absolutely free.

Come along to Crash, Bang, Squelch! to see lots of exciting hands-on science experiments! You can have go yourself and find out lots about why things work they way they do!

Our experiments will show you why hot air balloons stay up, what happens when you split water in half, how your lungs work, and much, much more...

Usually, we also be run a series of talks in a lecture theatre next door to CBS!, with lots of exciting experiments that are just too big to fit into the normal lab.

Times are listed on this year's event page: pre-booking is not required, just show up and be amazed!

Please note that CBS! is usually very popular, and during busy periods we are likely to be issuing timed tickets for later in the day to prevent large queues for the event. In 2010 and 2011 we ran out of tickets at around lunchtime, so get here early to avoid disappointment!
